CUSTOM SCALING

For alternative scaling to the standard 0 - 1000, cut Link 8

and short Link 7. Add two resistors R12 and R13 which

will set the basic scale of the meter. The highest practical

value for the R12 and R13 series combination is 12R . To

select your desired scaling, use the following formula:

R12 + R13 = Full Scale reading at 20mA

160

Re-calibrate as necessary.

A loop powered indicator giving an accurate, zero corrected indication of 4-20mA loop current. Calibration is by two 20-turn cermet

potentiometers which allow sensitive adjustment of the instrument. The meter is housed in a robust carrier, which can be bolted in

place or panel mounted using the low profile bezel and clips provided.
